PRITZ, OF GERMAN- TOWN, PENNSYLVANIA,ASSIGNORS OF ONE-THIRD T0 JAMES DELPHIA, PENNSYLVANIA BEVERAGE MIXERANI) DISPENSER Application filed September 15, 1928. Serial No.306,240..

The object of the invention is to provide improvements broadly inbeverage dispensing means, such as are automatically controlled by theuse of a coin of predetermined size or denomination, and whichdispensing means is ivholly independent ot anyvoutside agency for itscomplete operation after being properly supplied with the ingredients ofwhich the beverage or beverages are composed. l

More particularly the invention provides for the proper measuring ofdefinite quantitics ot any desired syrup with such a fluid as carbonatedwater under pressure, said syrup and Huid being mixed and dispensed intoa suitable container such as a :paper cup, which cup has been releasedfrom a magazine, and which cup when filled with a predetermined quantityoperates to release a door or other element, which until a given pointin the operation ot the device bars access to its interior.

Another object is to provide an ingenious arrangement of suitablemechanism, 'whereby the pressure from Within the Well-known carbonatedWater or other tank serves as t-he actuating means for the completeoperation of the said mechanism. upon its release by the application ofthe coin above referred to, said pressure no matter Wh at it may bewithin the tank being reduced to any desired operating pressure. andbeing operative after the com.- pletion of the cycle of movements toreset the mechanism so as to respond immediately upon the application ofa second coin, and so on until the tank is devoid of its fluid contents.

Further objects consist in providing novel means for the rejection bythe device ot any under-sized coin. that is for instance a cent or dimewhen the proper operating coin is a nickel; in providing novel means forthe -release of a cup from its magazine into operative position by andduring the operation of the fiuid controlling mechanism; in providingdoor release latch mechanism actuated by the cup upon becoming properlyfilled; in providing suitable retrigerating means for cooling the syrupand carbonated water; in providingr novel means for measuring` firstline 2 2 of Fig. 1 Fig. 3 is a section on the line 3 3 of Fig. 1; Fig. 4is a section on the line 4 4 of Fig. 1; Fig. 5 is a section on the line5 5 of Fig. 1; Fig. 6 is a section on the line 6 6 of Fig. 1; and Figs.7 and 8 comprise sections through a part of the operating portions ofthe device with the respective elements embodied therein shown indifferent positions corresponding With diierent phases' in the operationofthe mixing and dispensing mecahnism.

Referring to the drawings, an outside cabinet may be made of anysuitable shape, but in the present instance comprises a front Wall 1,having an -aperture 2, normally closed by means of a door comprising aframe 3 surrounding a preferably transparent panel 4, said door beingheld normally in closed position by means of a latch comprising an arm 5which is carried by one end of a rod 6, the central portion 7 of whichis curved in a substantially semi-circular shape and adapted to supporta cup or' other vessel 8 into which a beverage is dispensed and fromwhich it is drun'k by the patron or purchaser, the opposite end portionsof the rod 6 being journalled in opposite portions of a` transverselyU-shaped casing 9, having an open side which registers with the opening2 in the cabinet Wall 1 and a closed bottom 9. This same front Wall 1 isalso preferably provided with an aperture 10 through which used cups arethrust after serving the function for vrlii ch they are designed, anL-shaped tube 11 heilig secured to said front- Wall in communicationwith the aperture 10 and being directed inwardly and downwardly so as todis charge the used cups into a Waste container 12, removably positionedWithin the cabinet and resting upon the lowermost wall 13 of the latter.It will also be noted that a drain tube 14 leads from the lowermostportion of the cup surroundingI casing 9 towards and so to direct liquidwhich may spill within said casing into said waste container.

Preferably, in the upper portion of the cabinet and adjacent to the rearwall 15 is a compartment surrounded by heat insulation material 16 anddivided into two sections 17 and 18 for the respective cooling of thecarbonated water or other diluting agent and the syrup or other basefrom which the beverage is formed. The heat insulating material 16 maybeof any suitable type such for instance as cork, mineral wool. or thelike, and it is confined between the rear wall 15 and the wall 19 of ashell which also comprises end walls 20 in spaced relation with theparallel side walls 21 of the cabinet and an irregular inwardlypositioned wall Q2 in spaced relation with-a correspondingly shaped wall23,

.extending across the interior ot said cabinet between the sides Q1 otthe latter, substantially as shown in horizontal section in Fig. 2.Access'to the compartment Sections 17 and 18y may be gained through oneor more double walled closures Q4, including a layer ot' heatlinsulating material 25. rlhe lower portion of "these compartmentsections is closed by means oele a double walled bottom 26 alsoembodying a layer ot' heat insulating material 27. i y lllithinthecabinet, thus described, there positioned'adjacent to the front wall 1and above theaperture 2, any suitable form of cup magazine 26. adaptedto support reserve cups 29 from which the lowermost cup 30 drops intothe position shown in l, 2, 3 and 6 by any ,suitable type ot releasemechanism actuated by ay lever 31, connected by means ot a; chain 2Qover a pulley 33 with variable positions 34 upon an actuating leverpivotally carried at 36 by a block 27 secured within and by the adiacentwalls ot the cabinet and actuated as hereinaiiter described.

pening' through any suitable portion et the front. wall 1 is thereceiving end 38 of a coin chute 39. which is provided al; any suit ablepointwith a laterally curved portion 4l), having a 'laterally disposedelongated opening 41 adapted to permit coins ot sizes smaller than 'thatfor which the apparatus is designed to operate to tall from said chuteinto any desired position or receptacle. whence they can be removed bythe one operating the device. @n the other hand. coins of the propersize or denomination continue downwardly through said chute until theypass therethrough and into any suitable {"orm ot receptacle Yl'rom whichthey too can be re,- moved by the owners or lessors ot the device. aftersucn `coins have actuated the arm #l2 of a lever which is pivotallysupported at 48 by any suitable medium. and also compri: a second arm 44having a cutaway portion providing a shoulder 45, said lever beingyieldingly maintained in its normal position with the irst arm 42 inraised elevation by means of a spring 46, the tension of which isadjustable in any suitable manner as for instance by means of the setscrew 47.

Pivoted at 48 a lever having an arm 4f) which normally engages saidshoulder 45, and a second arm having an angular shape so as to provide.a seat 50, in and against which rests a link 51. through the medium ot'an anti-friction roller 52. The lever arm 4f) is vieldingly maintainedin its normal position by means of spring 53, while the link 5l. ismaintained in extended relation with respect to the arm 5l ot a lever bywhich it is pivotally supported at by means of a .spring 56, carried bysaid last-named lever.

The lever arm 54 extends beyond a supporting pivot 57 and is integralwith an oppositely extending arm 58. terminating in a flattenedextension 59. through which extends an aperture 60 for a purposehereinafter described. The arm 54 of this last-mentioned lever isprovided with an L-shaped rest 61, upon which the lower free end portionof a rod 62 is adapted to move. but is prevented from moving beyond saidrest in one. direction by a wall 63. the longitudinal movement ot saidrod 62 being freely permitted, while its transverse movement isrelatively limited by a bracket 64 through an aperture in which said rodslidably extends. Also. the lower portion ot said rod is vieldinglypositioned` adjacent to the rest 61 by means ot a spring 65 carried bythe lever arm the arrangement being such that when said lever arm isdepressed. the lower free end ot' the rod (El) rides relatively upwardlyand over the rest 6l so that the rod is moved upwardly as the lever armmoves in that direction, said rod. however. at a predetermined point inits upward movement being'removed trom engage` ment. with the rest 6lsaid rod engages one side of the aperture 64 in the bracket 644thrfnigli which it extends.

The oppositely extending lever arm 58 is provided with a laterallyextending' pin 66 which is adapted to be engaged by a shoulder 67 ot anotched portion ot a lever arm 69. pivotally supported at 69. andprovided with oppositely extemlinellattened and weighted portions 70 and71 respectively. said flattened portion being in alignment with theaperture 60 in the 'flattened portion 5.() ot the lever arm 56 and inspaced relation therewith. Elaid lever arm 58 is also connectedadiustably ".vith the. lower end portion ot a rod 72. while upon its l"tened portion .'f

and in axial alignment .th the a portare llt: is a spiral compressionspring' 73. through which slidahlv extends a link 74 carrying anadjustably positioned nut or op 75 and supported by the lower endportion ol a niston rod 76. l

The exp-f 76 is provided with a laterally projecting arm 77 in alignmentwith and adapted to engage the actuating lever 35 to trip the latter andrelease the cup 30 from the inagazine 28 at a predetermined point in theoperation of the device. Said piston rod is also provided with alaterally extending arm 78, said last-named arm as the piston rod risesbeing adapted to engage the diagonally directed tree end portion 79 ot arod 80 which. ata suitable locality, is provided with an elongated slot81 through which slidahly extends a pin 82 by which said rod is carriedby a bracket 83, the uppermost free end portion of said last-named rodbeing ed to engage. the shoulder 85 of a reciprocat-orv rod 80. which inturn is connected to the stem 87 of a normally closed valve 88;

The piston rod 7 (passes into a cylinder 89 through a head 90 and isprovided with a piston 91. which with said piston rod is normallymaintained in its uppermost position against the stop 92 by means of aspiral compression spring 93 Surrounding said lastnanied rod within saidcylinder. The upper portion ot said cylinder extends beyond the stop pin92 and terminates in a closed end 94, provided with an air escapeorifice 95, adapted to be closed normally by a suitable closure 3U 98,carried by a float 97, while the sides of said cylinder are providedwith apertures connecting with inlet and outlet tubes 98 and 99,respectively, preferably a slight distance above the uppermost limit ofmovement of the piston 91.

Within the cabinet is removably positioned any well-known type ol tank100 which is normally connected at 101 to one end of a coil ol pipe 102,positioned within the cooling compartment section 17, said coilcommunicating through a pressure-reducing valve 103 with a pipe 104,which leads through a normally closed valve 105, through a pipe 10G, toa T coupling 107 of a special construction, the valve 105'being normallyclosed by means ol a valve actuating stem 108, which is engaged by asuitably mounted bell riantY lever 109. which latter at its 'free end isoonnected with the rod 72, in turn adjustably connected at its lower end72 with the lever arm t l lll-fi thin t e;

lili

second, cooling compartment section is positioned syrup tank, 'fromwinch leads a pipe 110, which communicates through a normally open valve111 and through a pipe 11i? with 'that c et the rPIi'lJ i" lo TWf lbeni, wjt

er por auove reierrct, there is positioned a e interior oi? the throughthe i, ithin said T ball valve 115i, wliich, 111 is open, is adapttheentrance to said T trom the i vent syrup trom flow-- S41ed pipe insteadoi passdiagonally directed at 84 to form a lug adaptto the pipe 100,said ing through said T and laterally therefrom into the cylinder 89. Onthe other hand, at aY later time in the operating cycle of the device.when the valve 111 is closed and the valve 105 is open, the pressure inthe pipe 106 is operative to force said ball valve 113 upwardly so as toprevent the water within the pipe 100 under pressure from passing up-'ardly into the syrup supply pipe 1-10, but instead directing said waterlaterally into the cylinder 89.

The valve 111 is provided with a valve stem 114 which is operated by alever 115, having its outer end connected by a spring 116 to one end ofa lever 117, in turn piv otally supported at 118 upon the bracket 83,the opposite free end ot said last-named lever being adjustablyconnected with the rod 62. The rod 80 also supported by said bracket isnormally held laterally outwardly by means of a spring 119 in suchmanner that as said rod 80 is raised, its offset 84 engages the shoulderabove referred to. 1t will also be noted that the lever 117 isyieldingly maintained in a predetermined position by means of a spring120 connected with any suitable fixed point, and which last-named springis of a different degree of tension than the spring 116, extendingbetween the lever 117 and the valve stem actuating'lever 115 ot' thevalve 111.

1n the operation ot this device, the respective elements as shown inFig. 1 are in a position of rest and are set for the complete operationof the device. The pressure in the tank 100, when the latter is filled,is one hundred and titty (1K0) pounds to the square inch or thereabouts,tnough the effective pressure in the pipe 104 is reduced by the valve103 to any desired extent as for instance to sixty pounds to the squareinch. Ice or other suitable refrigerating medium is placed within thecompartment section 17 so as to chill the coil 102, valve 10S, andadjacent syrup tank in the compartment section 18. The cup is not inposition, though it is shown in dotted lines, but instead comprises thelowermost cup 30 suspended by and from the magazine :28. The valvepositions are as shown in Fig. 7 and the syrup by gravity is assumed tohave passed through the pipe 110, valve 111, pipe 112, and T 107 intothe upper portion of the cylinder 89 above the piston 91 in itsuppermost position` until the float 97 has risen sufliciently to closethe air escape aperture. 95 and thereby prevent further syrup fromentering said cylinder. i

l coin ot proper denoniination, as for instance a live cent piece, isinserted into the receiving end 38 of the coin chute 39, said coin inpassing downwardly finally dropping upon the lever arm 4Q which ittrips, with the result that the leve arm 4-9 is released by the shoulder45 and the link 51 di'ops,4pe11nit ting the lever arm 51 to drop, andraising the lever arm 58 upwardly. The lower end of the rod 62 isthereupon received by the rest 61 and the pin 66 engages t-he shoulder67 of the lever arm 68, the weighted arm 71 having simultaneously raisedthe flat-tened portion 70 of said last-named lever. The upward movementof the lever arm 58 raises the rod 72 and thus opens the water supplyvalve 105, raising the ball 113 to close the syrup entrance 112 at theupper end of the T 107. The pressure of sixty pounds or thereaboutswithin the line 104-106, forces the piston 91 downwardly to the positionshown in Fig. 8, the piston supported arm 77 engaging the lever 35,which, through the chain 32, operates the lever 31 to release the cu 30to drop into the position 8 supported by the centrally curved portion 7of the latch rod 6. The nut or stop carried by the link 74 engages thespring 78 as the piston rod moves downwardly, thus storing pressurethrough the compression of said last-named spring and finally passes andextends through the aperture 60 in the lever arm 58 and engages theflattened portion 70 of the lever therebeneath, with the result that theshoulder 67 becomes disengaged from the pin 66, whereupon thecompression of the spring 73 forces the lever 58 suddenly downwardly, sothat the upward movement of rest 61 forces the rod 62 upwardly, tiltsthe lever 117 tensioning the spring 116 and closing the valve 111. Also,the lever arm 58 in lowering depresses the rod 72 and closes the valve105, thereby stopping the inflow of the diluent such as carbonatedwater, or other liquid, under pressure, through the T 107 and into saidcylin-- der 89.

The lever 117 also lowers the rod 86 and opens the valve 88, thuspermitting the combined charge of water and syrup within the cylinder 89to be ejected yby the piston 91 under pressure of the spring 93 inte theswirl cup 121, whence the mixed fluids pass by gravity through adischarge pipe 122 into the cup 8. The lever 117 in lowering the rod 86permits the shoulder to be engaged by the notched end 84 of the rod 80,thereby holding the valve 88 open until'the beverage is delivered to thecup. The piston rod 91 in rising carried the projecting arm 78 upwardlyand thereby, upon the ejection of the beverage, engages the end portion79 of the rod 80, which releases the shoulder 85 and permits the valve88 to close. This movement also permits the valve 111 to open and pass asecond charge of syrup into the cylinder 89, the air therein escapingthrough the port 95, as the float, upon the cessation of the upwardmovement of the piston 91, drops with the outflow of the syrup upon thestop pin 92. Also with the reopening of the syrup valve 111, the ball113 drops to its lower seat and permits the syrup to How into saidcylinder until again arrested by the float closing the port 95.

As before mentioned, when a predeten.

mined quantity of beverage has entered the cup 8, its Weight tilts therod 6 so as to raise the arm 5 free from engagement with the door frame3, after which the purchaser is free to open the door and remove thefilled cup from its rack. The door 3-4 is preferably returnedautomatically by a springhinge 123, or the like, to its closed positionand after one hasconsumed the contents of the cu 8, the latter may bedeposited through the ca inet aperture 10 and tube 11 into the wastereceptacle 12. This operation may obviously then be repeated as manytimes and as frequently as desired and .until the supply of syrup andcarbonated water or other diluent have been exhausted, after which theymay be replaced and the operation of the device proceeded with as beforedescribed.
